Also another question - does AFM hurt the performance aspect of the car?

as pertaining to the AFM thing.
no it wont hurt the performance of your car. it only kicks in at times of low stress on the motor. so if you have your foot in it you arent going to be gimped by it. when i drive our new tahoe with afm, i cant even tell the difference. It shifts modes so seamlessly that i can only tell by the little gauge in the DIC.
